LIFTING CAR DUMPER.

Application filed June 22, 1925, Serial No. 38,638. ReneWed March 3,1927.

tically movable cradle cross-head and for the vertically adjustable panor a' chute supporting girder by which the construction of the guidecolumns is simplified and-the cost 01 construction ismaterially.reduced.

Further objects are to provide a mounting for the pan girder such thatless clearance is required bet-ween the ends of the cradle and the guidecolumns, such that the discharge pan or chute may extend completelyacross the space between the guide columns and such that the girderadjusting devices may be so positioned as to be efi'ectually' protectedagainst damage by impact of material discharged from a car on thedumper.

A further object is to provide a mounting for the pan girder in whichthe girder bears againstthe front face of the column and by which thelateral thrust of the girder is directly upon the column, and further toprovide a bearing for the girder on the column such that the lateralthrust on the column is substantially in the plane of the web thereof. I

A further object is to so mount the pa girder that it can be easily andquickly detached from the column without disturbing the guide members onthe column.

lVith the above and other objects in view, the invention may be said tocomprise the device as illustrated in the accompanying drawings,hereinafter described and particularly set forth in the appended claims,together with such variations and modifications thereof, as will beapparent to one skilled in the art to which the invention appertains.

Reference should be had to the accompanying drawings, forming a part ofthis specification, in which Fig. 1.is a side elevation of the cardumper; Fig. 2 is a fragmentary front elevation showing the upperportion of the tower and the pan girder supported thereon; Fig. 3 is afragmentary front elevation on an enlarged scale showing one-end of thepan girder; Fig. at is a horizontal section through a guide column andthe head carried by one end 01 the pan girder; and Fig. "5 is a verticalsection through the pan girder and upper portion of the chute.

Referring to the accompanying drawings, the car dumper comprises a tower1 built adjacent the edge of'the dock 2 and having supported thereon atilting crade 3 which is adapted to receive a railway car, the cradle 3having the usual supporting and guiding members 4, which are mounted forvertical movement between the front corner posts or columns of the,tower, this cradle being suspended from horizontal pivots 6 whichconnect the same to the guide members 4.- A horizontal pan girder 7 ismounted on the tower for vertical adjustment thereon and has fixedthereto a hook 8 which is adapted to engage with the pivots 6 of thecradle to limit the upward movement of the guide members .4. The pangirder 7 supports a discharge pan or chute which consists of an upperfixed section 9 extending along the top of the girder 7 and a pivotedsection 10 which extends outwardly from the lower edge of the fixeddeflector 9. The cradle 3 is operated by suitable hoist cables, as iscommon in the art, to elevate the same until the pivots are engaged bythe hooks 8 and to then tilt the cradle about these pivots to dischargethe contents of a car thereon onto the discharge chute.

. The operation of the car dumping cradle and discharge chute is exactlythe same as that of lifting car dumpers now in common use, the presentinvention relating to the mounting of the cradle cross-head and pangirder on the tower. In accordance with the present invention, both thecradle crosshead and the pan girder are mounted for vertical movement onthe guide columns 5, which formthe front corner posts of the tower 1.Each of the guide columns 5 is formed of four angle iron corner posts'11 to which are attached front and rear side plates 12 and 13 and aninner side plate or web 14 which has'vertically disposed angle guidebars15 and 16 attached thereto, which form between them a channel guide forthe guide members i. A third angle guide bar 17 is attached to the innerside plateld along its outer edge, the guide bar 1''? having one flangesecured to the plate ll and its other flange projecting inwardly fromthe guide column adjacent the front face thereof. The pan girder 7 hasrigidly secured to the opposite ends thereof vertically disposed heads18 which are positioned in front of the guide columns Above and belowthe girder 7, the heads 18 have secured to the inner sides thereoftransversely extending angle bars 19 which projects beyond the rear sideof the girder 7 and have rigidly secured thereto, vertical guide bars20', each guide bar 20 having an outwardly extending flange which liesupon the rear side of the inwardly extending flange of the guide bar 1?on the adjacent guide column. The cooperating guide bars 17 and 20 serveto guide the pan girder 7 along the front faces of the guide columns 5,wear plates 21 and 22 being provided on the front side plates 12 of theguide columns and on the rear sides of the pan girder. By mounting thecradle cross-head directly between the guide columns 5 and by guidingthe pan girder along the front faces of the guide columns it is possibleto employ a guide column of very simple and relatively inexpensiveconstruction.

By reason of the fact that the wear plate 21 extends along the frontface of the column directly in front of the plate or web 14, the lateralthrust of the girder is directly transmitted to the column in the planeof the web so that torsional stresses such as occasioned by thrust onprojecting guide members are eliminated. If for any reason it is desiredto detach the pan girder from the column, as, for instance, to replacewear plates 21, it is only necessary to detach the short guide flanges20 carried by the heads Vertically disposed adjusting screws 23 aremounted on the guide columns 5 upon the front sides thereof and thesescrews engage with suitable nuts 24: secured to the heads 18 beyond theends of the girder 7. The screws 23 may be provided-with suitable meansfor rotating them in unison as is common in the art to raise or lowerthe pan girder. The screws 23 being in front of the guide columns andoutside of the inner walls of the vertically disposed heads 18, areeffectually protected against damage by the impact of materialdischarged from a car on the cradle. In addition, the adjusting screwsand nuts are more readily accessible and the removal thereof for purposeof repairs is greatly facilitated.

Y By mounting the grider adjusting means outwardly of the inner sides ofthe guide columns, less clearance is required between the ends of thecradle and the guide columns and the discharge pan or chute maycompletely bridge the space between the guide columns. Furthermore, theguide columns are of simpler construction and are cheaper to erect.

Having thus described my invention, 1 claim:

1. in a lifting car dumper, a tower having guide columns at the frontthereof, a cradle mounted for vertical movement between said columns, avertically adjustable pan girder having end portions movable along andbearing against the front faces of said columns, vertical guide memberson the inner sides of the columns, and guide members on the girder andcradle co-operating with the guide members on i the columns. v
